+Week 2 Laser
+
+This week we focus on tools, and we learn about images.
+
+1. Coordinate system
+
+Last week we used the Absolute Coordinates system. This week we get some practice using the *Current Position*, as well as *User Origin*.
+
+Additionally, we will learn how the *Print and Cut* feature can be used to recover cuts that may have gotten out of alignment.
+
+2. Tools
+
+We will create a *speed/power grid* that we can use any time we are working with a new material in order to tune our settings. This tool will help us to find pleasing levels of "grayscale" that we can use in our fills.
+
+Learn to create a *settings library* that you can save and keep for your use.
+
+Exercise: Fake Transparency
+Overlap two fills. Learn to create a boolean difference between them. Use selections from your speed/power grid to make it look like the overlapping fills have transparency.
+
+3. Images
+
+Learn the difference between grayscale images and dithered images. Learn when is the best time to use each.
+
+Dithered images are technically black-and-white images that "fake" grayscale via the patterns they employ. These are good on all materials, including those that have a very narrow flashpoint, such as acrylic. (Grayscale does NOT react well on acrylic)
